As major institutional investors rebalance their portfolios ahead of year-end, Nomura Asset Management executed a series of strategic reductions in leading US energy firms. According to reports, the firm reduced its stake in Williams Companies by 12.1% and trimmed its holdings in Targa Resources by 10% during the fourth quarter. Additionally, Nomura sold 8,722 shares of Marathon Petroleum, despite the company reporting strong first-quarter results that surpassed market estimates.

Nomura's move comes amid a period of mixed performance in the energy sector, where Marathon Petroleum (MPC) reported earnings growth driven by robust refining margins, while Targa Resources maintained high institutional confidence with a 92.13% ownership rate. Per market data, peers such as Valero Energy and ONEOK have seen varying investment flows during the same period, highlighting a selective approach by asset managers toward energy infrastructure and midstream assets.

Traders should monitor current price levels, with MPC closing at $175.40 and WMB at $42.15 (close June 1, 2026). Looking ahead at the economic calendar, the API Crude Oil Stock Change reported on May 27 showed a decrease of 2.8 million barrels, which may influence sector sentiment. Upcoming data from the Dallas Fed Manufacturing Index will also be a key catalyst for assessing energy demand in major industrial hubs.
